Hydrangea serrata: varieties with photos and names, reviews


Serrated hydrangea is a type of garden culture. It is especially popular among domestic gardeners. And this is not surprising, because the plant has a lot of advantages, among which, in particular, it is convenient for the formation of a crown, cold resistance, high phytoimmunity, and unpretentiousness. With elementary care, the bushes grow rapidly and annually delight the summer resident with lush beautiful flowers of delicate shades.

Description of serrata hydrangea

Hydrangea serrata is a bushy, deciduous shrub. The root system is fibrous, spreading, up to 40 cm deep. Thanks to this feature, the plant quickly reacts to both fertilization and soil contamination. The leaf plates are green, oval, pointed at the end. Their length is 10-12 cm. There are notches along the edges, like a saw.

Most varieties of the serrated hydrangea bloom from July to September. However, in regions with a cool climate, budding may decrease until August. The diameter of the inflorescences varies between 8-15 cm.

Hydrangea serrata is a thermophilic plant native to Asia.

How serrated hydrangeas differ from large-leaved

The difference between these species lies in the shape of the inflorescences. In large-leaved hydrangea, they are usually spherical and consist entirely of sterile flowers. The serrate has corymbose inflorescences. In their center there is a large number of small flowers capable of cross-pollination. Along the edges are larger, four-leafed sterile flowers that do not have reproductive organs.

Important! The serrated and large-leaved hydrangeas are the closest relatives, so they are very similar to each other.

Varieties of serrata hydrangea

Since hydrangea has a long flowering period, hedges are often made from it, they are planted along the fence and near the walls of houses

Low-growing varieties are grown in pots.

Often, hydrangea compositions are placed in separate groups. However, they also go well with other ornamental plants. Hydrangea looks good next to birch, maple, acacia and lilac, as well as willow, bird cherry, barberry, jasmine. Dahlias, roses, peonies, starfish, rhododendrum, azalea, astilbe are also suitable for her,

Important! It is undesirable to plant a serrated variety of hydrangea near coniferous evergreen trees. This combination brings disharmony to the perception of the composition.

  • Bluebird - 20 ° C,
  • Koreana - 25 ° C;
  • Preciosa - 20 ° C;

Care and cultivation of serrata hydrangea

In order for a plant to grow and develop correctly, it must be treated with special attention. First of all, you need to choose the right place for planting, root the seedling. In the future, after this, one must not forget about constant care. Without it, the hydrangea stops blooming and begins to hurt, gradually die.

Selection and preparation of the landing site

The serrated hydrangea does not tolerate direct sunlight. Under them, her petals become too pale. However, serrated hydrangea is not suitable for full shade. Excessive darkening can cause bushes to stop blooming. The best option is partial shade. Hydrangea should be planted in places protected from strong winds. Landing close to the building is undesirable, since in this case freezing in winter is possible.

A few days before planting, the site is dug up. The soil overgrown with weeds can be pretreated with herbicides in 2 weeks. Serrated hydrangeas love light, acidic soil that is rich in humus. They do not tolerate high lime and ash content in the earth, as it reduces acidity.

In cases where the soil is heavy and has a poor composition, a ready-made substrate is bought in advance for planting in a garden store. Some summer residents make it on their own. For this, crushed high-moor peat, turf, humus, black soil and sand are mixed in equal proportions.

Landing rules

A landing pit is made in advance. Its size should fully correspond to the size of the plant's root system. The optimum distance between the pits is 1.5 m.

The very procedure for planting a serrated hydrangea variety is simple. Water is poured into the pit and a seedling is placed. Then it is covered with earth or a pre-prepared substrate. The land near the planted plant is lightly tamped and watered. Finally, lay a layer of mulch about 10 cm thick. For this, needles or sawdust are used.

The serrated variety of hydrangea is recommended to be planted in spring or autumn.

Watering and feeding

Most serrated hydrangea varieties need regular watering. It is especially important to carry out this procedure during heat and drought. Plants are watered as the soil dries up at the root. The water should be at room temperature. If it is too cold, it needs to be warmed up. The chlorinated liquid should settle for some time. The use of rainwater is encouraged.

Under the bushes, you need to fertilize twice a year, first before and then after flowering. At the beginning of spring, 20 g of urea is dissolved in a bucket of water and the hydrangea is poured with the resulting liquid. For each bush, 3 buckets of solution are consumed. After the end of flowering, the hydrangea is fed with complex mineral fertilizers.

Important! If the land is depleted, during the summer, you can additionally feed the bush with slurry. However, in this case, it is important not to overdo it, otherwise thin branches may break under the weight of a large number of large inflorescences.

How to prune a serrated hydrangea

The most suitable time to prune a plant is March. Shoots are cut in such a way that 6-12 of the most powerful ones remain. The remaining branches are shortened by several buds (up to 5). Pruning the serrated hydrangea in the fall involves removing the wilting buds.

Only old bushes need radical pruning. They are shortened in such a way that stumps up to 8 cm high remain above the ground. It is not dangerous and even useful. After such pruning, new young shoots grow, which bloom profusely.

Preparing for the winter serrata hydrangea

In the fall, the bushes need to be treated with chemicals against insect pests and all kinds of infections. When all the foliage has fallen from the bush, and it becomes completely naked, it should be sprayed with a 3% solution of Bordeaux liquid. If you need a serrated hydrangea transplant, then this can be done in the fall.

Most serrated varieties have very good frost resistance, but despite this, they still need shelter for the winter. First you need to add superphosphate and potassium salt to the hole. Then you should tie the shoots into a bunch and bend them slightly to the ground. Finally, cover the plant with two layers of spunbond. The procedure is best done before freezing begins.

Reproduction

The serrated type of hydrangea can be propagated by seed, dividing, layering or cuttings. The last method is the most popular. Cuttings are usually cut from young shoots of young bushes. Traditionally, the middle part of the shoots is used, on which there are no flowering tops and lower leaves.

In order for the roots to grow faster, the cutting is placed in water with a root former (any). If this is not available, honey is added to the water (1 tsp per 250 ml). The cuttings are planted under a shelter, and in the spring, already rooted plants are transplanted to a permanent place.

For reproduction by layering, an adult bush is chosen. With the onset of spring, before the buds bloom, its lower branches are pressed to the ground, pinned, and the place of contact is sprinkled with soil. By the fall, these branches will take root. New plants are transplanted to a permanent place in the spring.

Seed propagation is usually practiced by breeders during their experiments. Specimens grown from seed material often do not adopt parental qualities.

Cuttings are a reliable and effective way of propagation of the serrated hydrangea

Diseases and pests

Excess calcium in the soil is fraught with the development of chlorosis of serrate leaves. If the green mass begins to turn yellow or pale, it is necessary to use a foliar fertilizer, which includes iron. In this case, it is important to acidify the soil by introducing peat, crushed bark or ammonium sulfate into it.

One of the most widely spread pests is aphids. The main signs of its presence are damage to young leaves, the development of fungal diseases. If the number of aphids is small, it is destroyed by natural enemies - the lacewing and ladybug. You can fight a large invasion with a homemade decoction. They do it like this: 1 kg of raw or 200 g of fresh nettle leaves, chamomile flowers or dandelion roots are poured with boiling water and allowed to brew for 24 hours. If that doesn't work, use an insecticide.

Conclusion

Serrata hydrangea is an ornamental shrub with delicate flowers, which often becomes the main decoration of the garden. The plant is not at all whimsical to growing conditions and care. Even inexperienced summer residents can cope with this. If you follow the elementary rules of agricultural technology, the plant will delight with its beauty for many years.

I have been growing hydrangeas in my garden for over 10 years. Throughout this period, the plants annually delight me with beautiful and fragrant inflorescences. I like the fact that the shrub is unpretentious, easy to care for. I apply fertilizers to damp ground so as not to burn the roots. Last year I used Buiskie Fertilizers. After them, the pink inflorescences acquired a rich blue hue. I was only pleased with such a variety.
